Rotors turned, how long will they last?

[KJ zGal]

So, after having the rotors turned on the KJ, any estimates as to how long they'll last before they start warping again, and need to be turned a second time or potentially replaced altogether? Just kind of curious...

stock rotors approx 30k, but mostly depends on your driving habits and daily routine.

Anywhere between 20-30,000 miles. Depends on your driving habits..

Mine warped right away.

I think that is hard to say. I dought that they could be turned a second time and be in spec. When rotors are turned material is taken off in order to make the surface smooth, and so the rotor is then thinner and the thinner it is, the easier it will warp. It won't dissipitate heat as well is all.

But since it is done, you will find out I guess. If you had it done at a reputable place, they would have not done it if it would not have been in spec, and told you to replace them. So they must not have been too bad. So you are ok if done at a reputable place. Where did you have it done??

Yeah not long, I replace mine every time. I am VERY ******* breaks. I drive the KJ like a ricer. I've put about 60-70k on my libby and am on the 3rd set of rotors. Luckily I can change them out in less than 15minutes per side.

But turning 'warped' rotors really doesnt fix the vibration your probably experiencing when under high pressure. The warp will come back because the metal is warped, not just the surface is bad. My guess is you'll be needing to completely replace the rotors within the next 20k for sure.

Is it only like $20 to have them turned? If so, Its probably worth it. I know I'm to ******* them to have them turned, my last set had started turning purple in the right light. (like they've been so hot they were starting to forge) and thats why they warp. Get hot, cool down, get hot cool down, and eventually, they arn't perfectly round anymore.

Sounds like you'll be fine though.

I would love some ceramics/slotted rotors, but they are so costly and again, The way i drive; it just wouldn't be cost effective.

Just wanted to let anybody getting rotors turned, be careful with Tires Plus, they messed up the front ones on my Durango.....their machine was out of tune. Not all Tires Plus's are bad, just be careful..

All depends on how you drive. I had mine machined down at 12k and they are still good at 38k. Dont plan on replacing them till the pads wear out which will be awhile.

I would not try to get them machined a second time.

there are tolerances so hopefully when they get that low, just buy new ones.

Well when I had them checked out the first time my mechanic said they didn't look like they'd ever been off before (and that was at 107k!), so theoretically they should last for one more turning if needed, but I guess it will just depend. Was definitely more expensive than I was anticipating, however. And Dave, I had them done at Alltech Automotive on Route 50 in Bspa--We've been going to them for years =]

You came all the way to BS to have Rick take care of you. You got no problem then. Don't worry about it. You are fine.
